The gelatinous, elastic membrane covering the sensory hair cells of the human ear is known as
a)	Basilar membrane	b)	Tectorial membrane
c)	Reissners’s membrane	d)	Neuro-sensory membrane

(b)

In the middle ear, the organ of Corti is a structure located on the basilar membrane which contains the hair cell that acts as the auditory receptors. The hair cells are present in rows on the internal side of the organ of Corti. The basal end of the hair cell is in close contact with the afferent nerve fibres. A large number of processes called stereo cilia are projected from the apical part of each hair cell. Above the rows of the hair cells is a thin elastic membrane called tectorial membrane
